Title: Vehicle furniture anchorages
Inventor: UNWIN CECIL NORMAN
IPC: B64D11/06
Filed: 1988-06-11
Abstract: A floor track (1) has an inverted T-section channel whose mouth, defined by flanges (2), has periodic enlargements between slots (4). A seat or other furniture is fixed to a bar (6) which overlies the track and which carries a member (8) with headed studs (9) on its underside and a spring loaded plunger (10). The studs (9) can enter the track channel through the enlargements (3) and, when shifted longitudinally, they become captive below the flanges (2). The plunger (10) can then engage in one of the enlargements. The member (8) has limited freedom of movement with respect to the bar (6), to allow for irregularities in track and/or furniture, and a clamping device (20, 22) mounted on the bar (6) can be actuated to urge the member (8) upwards and the bar (6) downwards, clamping the heads of the studs (9) against the undersides of the flanges (2). <IMAGE>

Title: A board game
Inventor: CARR PATRICK
IPC: A63F3/02
Filed: 1989-03-15
Abstract: A board game comprises a board divided into polygonal spaces, and playing pieces having sides allocated different values, wherein the orientation of the pieces in the spaces is significant and wherein pieces interact when in adjacent spaces in accordance with the value of their adjacent sides. The pieces may be square or triangular, and flat or pyramids. Colours are used to distinguish the side values, and the values may vary depending where on the board a piece is standing. The permitted moves include part-rotation of a piece in a space. As shown, each player has twelve pawns with sides of values 1, 2, 3 & 4. The board has a home territory for each player, a neutral territory and a central citadel area formed by four squares. Players attempt to remove opposing pawns and turn pawns into kings by reaching the opponent's base line. The winner is the one who occupies the citadel with four kings. The playing pieces may engage the board by peg or magnetism and caps may be placed on pawns to create kings. <IMAGE>

Title: Optical transmitter
Inventor: EPWORTH RICHARD EDWARD
IPC: H04B10/2507
Filed: 1990-07-03
Abstract: In an optical, e.g. soliton, pulse transmitter the pulse source, e.g. a solid state laser (11), is coupled to means for generating a series of time delayed pulses for each successive generated pulse. The delayed pulses which may be produced by multiple reflection of the laser signal between a pair of parallel plane mirrors (14, 15), are then combined (16) with the original pulse train. This generates a high bit rate pulse stream that may be modulated (15, 18) e.g. by omitting selected pulses, to transmit information. <IMAGE>

Patent GB-2249891-A (GB)
Title: Driving device for piezoelectric element
Inventor: SAKAIDA ATSUO
IPC: H02N2/00
Filed: 1991-07-11
Abstract: A driving device for a piezoelectric element is provided which attains lower power consumption, low heat generation and low cost. To displace a piezoelectric element, a first switching transistor Tr1 is rendered ON by a control circuit. The electric charges flow in the piezoelectric element from the power supply through the first switching transistor Tr1. This state is continued until a sufficient amount of electric charges are stored in the piezoelectric element. To restore the piezoelectric element thus displaced, a second switching transistor Tr2 is rendered ON under the condition where the first switching transistor Tr1 is OFF. In this condition, a resonance circuit is formed by the piezoelectric element and the coil 53. When the electric charges are flowing in the coil and a predetermined period of time has elapsed after the second switching transistor Tr2 is rendered ON, the control circuit renders the second switching transistor Tr2 OFF, whereby the current flowing in the coil flows into the power supply. <IMAGE>

Title: Defect position logging method used in assessing defect size
Inventor: YOSHIDA HAJIME
IPC: G06T7/60
Filed: 1992-01-22
Abstract: A method of assessing a defect is disclosed in which the video camera image signal of an inspected object is divided into zones. In each zone the brightness level is used to detect the presence of a defect (steps 1 - 5). The position of the first detected defect zone is stored and then the horizontal and vertical distances to the second detected defect zone are assessed such that if they are within a preset distance, it's position will also be stored. The distance between the second and third detected defect zones is then likewise assessed and so on until the distance to the next detected defect zone lies beyond the preset distances (steps 6 - 8). The size of the defect is assessed by the maximum horizontal and vertical distances between the stored defect zone positions (steps 9-10). <IMAGE>

Abstract: Shown here is a case (10) with easily removable wheels (11) and feet (13). These external fittings attach to the outside of the luggage shell and have a projection (92) which extends to an aperture (90) in the wall of the case shell to the inside of the case. A manually releasable latch (96), such as a clip, engages and disengages this projection from the inside of the case to mount the wheel and leg to the outside of the case. This attaching system also acts as an anchoring device (114) for the straps (116) normally used to hold and arrange clothing when packed inside the assembled case. This external fitment system is especially useful when the two shells (12) and (14) of the case are stored one within the other during shipping by the manufacturer and storage by the consumer.

Title: Improvements in or relating to radio communication systems
Inventor: HULBERT ANTHONY PETER
IPC: H04J13/00
Filed: 1992-06-25
Abstract: Code Division Multiple Access (CDMA) based on Direct Sequence Spread Spectrum (DSSS) permits good multipath diversity by the use of the so-called rake receiver. When multipath codes are sent over the some link (to increase the transmission rate for that link without altering the basic transmission format) multiple rake receivers would normally be required. This invention involves the rake combining operation prior to code correlation in order to make only a single rake processor necessary. This affords significant savings in complexity. <IMAGE>

Title: Mutiplyless discrete cosine transform
Inventor: KEITH MICHAEL
IPC: H04N7/30
Filed: 1992-10-19
Abstract: A method for performing a discrete cosine transform on a transform input value wherein the transform input value is operated upon only by shift operations and add operations to provide a discrete cosine transform output value without any multiplication. This method may be applied to both forward and inverse discrete cosine transforms. The transform coefficients are simplified coefficients which are provided by truncating and modifying prior art transform coefficients. The simplification of the coefficients causes degradation of a video image transformed using the simplified coefficients. Therefore the simplification is constrained to cause an acceptable amount of image degradation. <IMAGE>
